In addition to the hull and superstructure, there are several other features of a cruise ship that are located underwater. These features include the engine room, fuel tanks, crew cabins, crew quarters, fresh water reserves, and laundry room. The complete design of a cruise ship is built around the economics of the vessels and the needs, safety, and comfort of the passengers. All of the engineering decisions have been made with these factors in mind, and the results are the impressive cruise ships that travel the seas. Passengers do not have underwater cabins, as these areas are reserved for staff, ensuring ship safety and functionality.
Historical Perspective: Titanic vs. Modern Ships
However, there are cabins only for crew members to live and sleep in. Let’s take an example of the largest cruise ship, Symphony of the Seas, which weighs approximately 228,000 tons and would displace 228,000 tons of water. The N and V markings represent the ship’s classification society, ensuring adherence to international standards.
Environmental and Safety Implications
The drawback of a Displacement Hull is that the ships can’t go as fast as they might with a different hull shape. The rounded edges of the hull help to dissipate the drag or force of the water acting against the ship. Ships with Planing Hulls usually are designed to go faster than ships with Displacement Hulls.

Under Water Rooms for Passengers on a Cruise?
The weight of the ship is distributed evenly, with the heaviest parts of the ship located at the bottom. This means that the ship is more stable and less likely to tip over, even in rough seas. Generally speaking, smaller cruise ships tend to sit lower in the water than larger ones.

The wide hull design helps achieve this stability by distributing the weight of the ship over a larger area and allowing for a more significant amount of water displacement. This helps maintain equilibrium even in rough seas and ensures the safety and comfort of passengers on board. The wide hull design of cruise ships plays a crucial role in water displacement, allowing them to displace an equal amount of water to their weight. This design creates upward pressure, ensuring the ship remains afloat and stable.
Do Cruise Ships Have Staterooms Underwater?
Most modern cruise ships have a deep V-shaped hull, which is the most efficient shape for cutting through the water. The hull of a cruise ship is the most important part of the vessel, as it is responsible for keeping the ship afloat and stable in the water. The shape of the hull is designed to minimize resistance and maximize efficiency, allowing the ship to move through the water with ease. Fortunately, modern engineering makes ships much more stable by making them wider and lower in the water. The technology used to manage weight distribution via ballast tanks is also far superior and more responsive than it used to be. Cruise ships are designed to be very stable and have a low center of gravity.
Navigating Cruise Ships in Various Types of Water
Then there was Crystal Cruises, which fell to No. 4 in this year's voting after placing second in 2020. Your best option for seeing life in the ocean might be to book a glass bottom boat excursion which is designed purposely for comfortably seeing sea life in ideal locations. Finally, for the vast majority of the time, there would be nothing to see other than passing water. There is only one modernly designed ocean liner currently still in service, and that is the Queen Mary 2 (QM2), which is owned by Cunard. The Ocean Liner Queen Mary 2 has a maximum speed of just over 30 knots and a cruising speed of 26 knots.
The hull of a cruise ship is also designed to accommodate various features, such as cabins, crew quarters, ballast tanks, and the engine room. The part of a cruise ship that’s underwater, also known as the draft, varies with the ship’s size and weight. For large modern cruise ships, about 30 feet of the ship is usually underwater. Marine engineers have designed ships to displace enough water to keep them stable and prevent tipping. Modern cruise ships are equipped with technology and design features that ensure they displace enough water to create stability and prevent tipping.
Accommodations and Amenities Onboard
The 50 largest cruise ships in the world exceed a whopping 100,000 gross tons. To put that into perspective, that’s equivalent to the weight of approximately 71,000 standard-sized cars! The weight of these floating giants is necessary to ensure stability and balance in the water. There are different sections of modern cruise ships that go from the bottom deck up to the top, sometimes 20 stories above the water. In this article, we explore what goes on on the lower decks, get some facts and figures about cruise ship measurements, and understand how much of a typical cruise ship is underwater.
Most cruise ships have a mechanical stabilising system (referred to as stabilisers) that can be deployed when at sea. These take the form of extending fins that rotate and are able to impart a righting force when the vessel is moving ahead. The T stands for Tropical, the S stands for Summer and the W stands for Winter. But for practical reasons (this can vary as to the regions of the world and time of year) and on most cruise ships, the S load line is used.
As marvels of engineering, cruise ships demonstrate how meticulous planning and design contribute to a seamless and enjoyable cruise experience. With their emphasis on buoyancy, stability, and safety features, these vessels allow passengers to relax and enjoy their vacation, knowing they are in capable hands. Marine engineers have developed technology that ensures a cruise ship remains stable in the water.
Royal Caribbean International owns the four largest cruise ships, and the average length of these vessels is an impressive 325 meters. To give you a sense of scale, that’s approximately 20% longer than the iconic Titanic. These colossal ships provide ample space for a wide range of amenities and activities, ensuring that passengers can enjoy a variety of experiences onboard.
The bulbous bow helps to push water out of the way as the ship moves through the water, reducing resistance and making the ship easier to maneuver. The Titanic was not equipped with enough lifeboats to evacuate all the passengers in case of an emergency. As a result, many people lost their lives when the ship sank after hitting an iceberg. Since then, regulations have been put in place to ensure that all ships have enough lifeboats for everyone on board.
With these marks, one can easily assess the ship’s draft, which is the depth from the waterline to the lowest point of the hull. This depth helps the sea voyagers to stay stable while providing enough buoyancy for them to float. Cruise Hive was established back in 2008 and among the earliest blogs in the industry.
